Product details

MEMS oscillator with 26.6 MHz CMOS output

The DSC1121DI1-026.6000 is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 26.6 MHz CMOS output. Its wide supply range of 2.25V to 3.6V lets it sit on a 2.5V or 3.3V rail without a separate regulator — one less BOM line to manage.

Enable/Disable for power gating

With the output disabled, the max supply current drops from 35 mA to 22 mA, saving 13 mA per clock tree branch.

Housed in a 6-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The 0.098" x 0.079" footprint matches the common MEMS oscillator land pattern — no via-in-pad needed, and the small body fits tight channel spacing on a multi-layer board.

Listed as Active by Microchip.

Frequently asked questions

What supply voltage does DSC1121DI1-026.6000 require?

The supply voltage range is 2.25V to 3.6V, covering common 2.5V and 3.3V rails. No external regulator is needed if your rail falls within this window.

Is DSC1121DI1-026.6000 RoHS compliant?

The evidence does not explicitly list RoHS compliance status. Confirm with the datasheet or your Microchip representative for the latest compliance declaration.

Does this oscillator have an enable/disable pin?

Yes, the Enable/Disable function is standard. When disabled, the max supply current drops to 22 mA from 35 mA, allowing power gating of the clock output.
